Rough estimate of 72 cell panels at 2m² and 500W per panel puts this at a peak performance of 25kw. More than twice the average home installation.
I feel like it could be great for running cooling systems on trailers and stuff like that, not sure if it would be worth the hassle for adding range.
Even on a purposely designed solar car like the lightyear one it really only works because they used all the weight saving and aero tricks possible, which you can't really do with a truck that's supposed to haul cargo.
20kwc capacity: nice also add 20kwh lithium storage at 200kg weight and it could help in few instances like cooling perishable cargo or driver's cabin when engine shut off, but definitely not to expand range
